Mention the fact that you're a senior when you first make your travel reservations. All major airlines and many Puerto Rican hotels offer discounts for seniors.
Though much of the island's sporting and nightlife activity is geared toward youthful travelers, Puerto Rico also has much to offer the senior. The best source of information for seniors is the Puerto Rico Tourism Company, or, if you're staying in a large resort hotel, talk to the activities director or the concierge.
